STATUS_LICENSE_VIOLATION
The licensing subsystem detected product-type tampering
This NTSTATUS has a narrow documented meaning: the system detected tampering with the registered product type. It should not be used as a catch-all explanation for every activation or entitlement failure. Product-type state belongs to the Windows licensing subsystem and is evaluated separately from ordinary application access control.
Capture the component that returned the status, Windows edition and servicing history. Verify system file and licensing-service health through supported tools. Do not recommend registry edits or binary patching intended to change product type; those actions can worsen the state and are outside the supported licensing model.
What to inspect
- Record edition, build, recent servicing or imaging changes, and the returning component.
- Check Software Licensing API/service state and related system events.
- Use supported repair, activation, or reinstall procedures; do not patch product-type data.
